There are many, many others, but spelling is sometimes a challenge. This website might be helpful; it seems much more accurate than many others - and has audio links, to hear how names sound, in Irish:www.babynamesofireland.com/irish-girl-names

But spellings and pronunciations vary - I'm in Scotland and here some of the names would sound a little bit different from the Irish versions. There's no 100% right answer!

Actually, I wouldn't go for Cameron as you already have 2 boys with C names. I think Lachlan goes really well with your other DCs names if it's a boy and maybe Brogan for a girl. You need to think whether you'd be happy with 2 island names if you went for Iona.

We have Icelandic, Irish (latter two are mine) and Scottish heritage, but don't live in any of those countries anymore, so a name with a very traditional spelling won't really work, probably. Two DC have Irish names, one Scottish, so probably aren't looking at Icelandic names, so it all flows better. DP has many of the names he likes in either his family or from bad memories of kids at school, so we've had to discount a lot of names that way.
